The Maine is going big for their 20th anniversary. The Arizona rock band recently announced the dates for the highly anticipated return of their 8123 Fest, and on Monday, the band dropped the lineup everyone has been waiting for.

The two-day Festival will take over Mesa Amphitheater in Mesa, Arizona, on January 15 and 16, 2027, and will feature The Maine as the headliner both nights. Fans will get a completely different show each night — no repeats! Joining The Maine on the lineup, curated by the band themselves, is a mix of longtime friends and artists, including The Band Camino, Andrew McMahon and the Strings Attached Quartet, The Academy Is…, Beach Weather, The Aces, and fellow Arizona artists The Summer Set and Sydney Sprague, with more acts rounding out the festival.

For O’Callaghan, the festival arrives at a pretty significant moment for the band. “Standing at the edge of 20 years as a band and that free-fall feeling of weightlessness is beginning to well up as the roller coaster climbs,” says O’Callaghan. “To say I’m excited would be the biggest understatement, and now we can finally answer the most-asked question of the year so far: 8123 FEST is a GO. So it’s time to shed the parkas for a light cardigan, clean off your golf clubs (I heard that’s a sport some people play), and mentally prepare for the most beautifully manic weekend that The Maine can provide. Lineup is juiced. Vibes are sky high. And YEAR 20 + 8123 FEST will make for some historic sh*t. Giddy up!”

Kirch says the festival’s significance goes beyond the music, particularly for a band whose relationship with its fans has grown over nearly two decades. “8123 Fest is all about the people that have created a family around our band,” adds Kirch. “Fans from all around the world getting together in our hometown, all celebrating 20 years of something that is much bigger than music. These people have become family over the past two decades, and we can’t wait to be together again! We are so proud and honored to announce the lineup for 8123 Fest 2027. These are bands we love and know are going to give everyone a show they will not forget. The goal this year was to level up the festival, and these artists absolutely do that. It is going to be an honor to share the stage with them.”

The weekend won’t stop with the two main festival days. Additional side shows are planned, with details still to come, along with a festival pop-up shop. A charity day is also scheduled for Monday, January 18, 2027, with more information expected later. Here’s a look at everything happening during 8123 Fest weekend (times subject to change):

The festival announcement comes during an already busy stretch for The Maine. Earlier this year, the band wrapped its first U.S. headline tour in nearly two years, which became the biggest on-sale of their career. They’ll head to Europe this fall for an eight-city headline run beginning in September, their largest European tour to date, while a new batch of U.S. headline dates is also underway.

That U.S. run kicks off August 20 in Tucson, Arizona, and spans 11 shows across the country, including stops in Anaheim, Chicago, Baltimore, and Worcester.

The band is also fresh off the release of their latest album, Joy Next Door. Released during what has become one of the biggest eras of The Maine’s career, the record was written and recorded sequentially, allowing the album’s songs to unfold as a connected story. It also continues the band’s tradition of assigning a color to each era, with green representing the Joy Next Door chapter.

Nearly 20 years into their career, The Maine has amassed more than one billion global streams and over one million social media followers. Since releasing their debut, Can’t Stop Won’t Stop, in 2008, the band has put out nine studio albums, with five reaching the Billboard 200. Along the way, they’ve played festivals including Bonnaroo and Lollapalooza and built 8123 Fest into a major homecoming for the band and its international fanbase.

With a 20th anniversary on the horizon, 8123 Fest 2027 looks set to be less of a typical festival weekend and more of a celebration of everything The Maine have built with their fans over the last two decades.

Having seen nearly every band on this lineup live, I can assure you — this is a lineup you will not want to miss! Grab your tickets while you still can and gear up for an unforgettable weekend of music, community, and 20 years of The Maine.
